Cochin Thread!!!

[Reyvaughn]

I have a question - a genetic question. I think I know the answer, but I want to double check...

I have 2 buff columbians that I thought had a serious DQ. Before I continue to grow them out, I need to see if the DQ can be fixed. A little story first...

I have a total of 5 birds from this breeder. The 2 buff Columbian cockerels have hard tail feathers, but yellow legs. My blue buff columbian cockerel has white legs. My 2 girls could be blue buff Columbians (lookslike blue in the tail, black in the hackles, so I am saying blue) and also have white legs. I don't know why, but the blue buffs have the white legs. Now, here's the question. My breeding roo is typey and has yellow legs. Yellow legs is dominant right? I am not sure I should take the chance on even keeping these girls because of the white legs. But, if yellow is dominant, I can breed it out, right?

i though white was dominant

Shank color


Dermis


Epidermis
White none (Id/Id) white (W+/W+)
Yellow none (Id/Id) yellow (w/w)
Green (Willow) black (id+/id+) yellow (w/w)
Slate/Blue black (id+/id+) white (W+/W+)
Black black (id+/id+)
white (W+/W+)

sorry, white is dominant over yellow. BUT would show up when the next generation is bred back to each other or to a yellow legged bird.

Okay, now if full (or at least same cockerel as father) siblings have yellow legs, these girls should only carry one white leg gene, right?

um... if one parent has white (homozygous W+/W+) and the other parent has yellow (homozygous w/w), then all the chicks will have white legs (heterozygous white W+/w). breed these chicks together and you will get 25% white legs (W+/W+), 50% heterozygous white (W+/w), and 25% yellow (w/w).

it's quite possible the white legged birds may already be heterozygous, W+/w, in which case bred to a yellow legged bird will produce 50/50 yellow and white.

this is not a sex-linked gene, so males and females will carry it equally.

wasn't sure what you were asking but i think i got there?

 

[Reyvaughn]

I wasn't asking if it was sex linked, because I have a blue buff cockerel from the same breeding with white legs (it seems the blue buffs have white legs, not gender specific, but color specific). Since I have white and yellow legged chickens from this pen/breeder, the white legged girls have to be W+/w is what I was asking. The father would have to be the yellow legged parent to have yellow legged siblings (half siblings, I assume) to these white legged girls.

So, if I breed to my yellow legged roo, the 50% yellow legged birds would be w/w and I'd never have to worry about white legs again, right? If so, then I'll keep them and use them. I wanted to make sure I could breed the white legs out without ever having it pop back up in future breeding.

yes, yellow is recessive, so if you have a yellow legged bird, then it's homozygous for w/w and no more whites will show up unless bred to another white legged bird.

I have a pair of nice bantam black cochins. So far I have had "0" fertility. They are both VERY heavily feathered. I haven't had any luck with the AI thing, so I am wondering if there is a link to some pictures, a tutorial or a video on the correct way to trim around their vents. I'm pretty sure this is the problem. My little hen has such a big badonkadonk I call her Donkey. I tried searching but what I have come up with hasn't been very helpful.

Thank you to anyone who can help. My hen is laying right now, so I would like to get some chicks out of her.

Donkey! Awesome name!

I have been plucking this year. Hate it but I started back a few months ago because everyone was hugely feathered this spring, for some reason. They have been fluffy before but this year it was unreal and I was having trouble with a few pens that had always been greatly fertile so I plucked and a few days later plucked some more and then the next week, I made them mad again by continuing to move to the sides a bit because I was still finding stuff in their fluff. Bless their little hearts, I will still plucking butts until I started seeing development in eggs. Those birds got to where they were backing into corners saying" Oh, no! Is that HER again?"
I have trimmed my whites before with scissors but so often catch up a bird when I do not have scissors handy and some seem to have no trouble with plucking, while others beg for me to get the shears....please! LOL
